DUMPING-CART.

SPECIFFCATION forming part of Letters Patent N o. 729,266, dated May 26,1903. Application led December l, 1902. Serial No. 133,487. (No model.)

To all whom, ibm/wy concern:

Be it known that I, ADAM BRENZINGER, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Dump-Cart, of which the following isaspecification.

This invention relates to improvements in dump-carts to be used fortransportingr sand,

earth, gravel, ashes, eine., and for discharging and distributing themat will.

The object of this invention is to enable the operator to discharge thecontents of the cart along the road at dierentintervals and so controlthe quantity of the discharge while,Y the cart is in motion. For thispurpose the 2 is a longitudinal section of the hoppershaped body withportions of the working mechanism of my improved cart drawn on a largerscale. Fig. 3 is a rear View of the body, showing the details ofmyimprovement. Fig. 4l is a longitudinal section of the lower part ofthe body, showing the slide-door in detail. Fig. 5 is a cross-sectionthrough the slide-door, showing the guideways for the sliding door indetail. Fig. 6 is a plan view of the rear part of the slide-door. Fig. 7is a front View of the axle, showing the frame of the cart forsupporting the same. Fig. 8 is a side View of the cart-support shown insection in Fig. 7. Fig. 9 is a rear view of the guide-rollers andbrackets, and Fig. 10 is a detail'side View of a lever working on themain shaft.

Similar letters of reference indicate corresponding parts.

l Referring to the drawings, a represents the hopper-shaped body, whichhas its front and rear walls inclined so as to slope downwardly towardthe middle or converge in such a manner that the angle of friction ofany material for which the cart maybe used is less than the incline ofthe sides. The sides of the body are vertical and parallel, as shown inFig. 3, or may also be inclined toward the middle. Between the lowerends of the front and rear inclined walls is an opening, and atthe'sides of the opening are guideways l, in which a sliding door b ismoved, which is provided at its upper end with projections m, to whichare attached one or more cog rails or racks by means of bolts.

The wagon-body may be made of any suitable material, as sheet-steel,iron, and wood, and it is preferable to have all rivets and boltscountersunk.

The sides of the wagon-body are connected bya transverse tube C,wedge-shaped in crosssection and with its sharp edge pointed upwardly.The tube is of such size as to allow the widest part of the axle to passfreely through it and is placed in or near a vertical line drawn throughthe point of gravity of the hopper-shaped body when loaded. The axle d,one end of which is shown in detail in Fig. 7, has behind its Wheel-seatrectangular enlargements, on which rest supports E, to which theenlargement of the axle is fastened by means of split keys f. Thesesupports E may be replaced by dat steel or spiral springs, if desired.These supports E are fastened by bolts or screws to longitudinal beams gg, which are connected to the wagonbox by angle-irons 7a h andtransversely by cross-pieces t' lo. The cross-pieces t' lc and beams g gform the frame of the cart, to which may be attached shafts for one or apole for two horses, supplied in the usual way with whifdetrees, rings,&c.

The guide-pieces l Z, in which the slide-door b moves, extend backwardfar enough to prevent a tipping over of the slide-door b when fullyopen. The two sides of the hoppershaped body extend inside of theslide-door sufficiently to prevent sand or other contents of the body tomake its way to the guideways Z. The front inclined wall of the bodyextends a triie down below the three other sides. The inside of theslide-door is beveled down just enough to slip underneath the lower endof the frontfinclined wall of the wagon-body to secure a tight closingofthe IOu bottom of the box. The cog rails or racks n, attached to theupper part of the slide-door b, extend upwardly to meet a correspondingcog-wheel or pinion o, which is fastened to a shaft 19, supported bybrackets q, which are bolted or secured to the under side of the frameof the cart or beams g. To the frame of the cart are also attached smallbrackets w, which support rollers Iv on axles 0c, which guide the rack nand hold it so as to engage with the pinion 0. To one end of the shaft pis fastened a hand-wheel or cross-lever r for turning the shaft p. Theopposite end of the shaft p extends somewhat beyond thesupporting-bracket q and is provided at its end with a washer and pin toprevent the slippingin of the shaft p. A levers swings around apivot-pin of the bracket q and has a width at least of that of thepinion 0. Itis adapted to be placed between the bracket q and the washerand pin at the end of the shaft p. The lever has a slit, which slipsover the shaft p when in position. When the lever is lifted out of theshaft p, theshaft can be shifted over, so that the pinion o disengagesfrom or clears the racks n. The slide-door b can then be moved to andfro independently of the shaft. If more than one rack be used, they maybe connected or secured bya tie-rod o in order to keep them at an equaldistance from each other.

The operation of my improved dump-cart is as follows: The sliding door bis in its downward position and the hopper-shaped body filled with sand,gravel, or other material and the lever s placed in its downwardposition between the end washer and the bracket q, so that the pinions oengage with the rack fn. The cart is then moved to the place ofrepairing the road, paths, doc., and the hand-wheel r turned, whichrotates the shaft p and pinions o, which engage with the rack n and movethe same upwardly. The slide-door b is thus opened to an extentdepending on the amount of rotation of the shaft p. Moving thehand-wheel r in the opposite direction will close the slide-door, sothat any amount of material may be discharged from the hopper-shapedbody, depending on the movement of the hand-wheel fr. It is obvious ifan entire discharge of the hopper-shaped body is desired the handwheel ris given a complete rotation or several and the slidedoor b therebymoved upwardly, so as to clear the opening in thelower part of the body.

The hand-wheel r may be replaced by a sprocket or gear wheel to whichmotion may be imparted by a chain and similar sprocket or gear wheel atthe front part of the wagon or at the seat of the driver. The body a maybe placed between the axles of a four-wheeled vehicle, in which case thetube C is superfluous and the hand-wheel may be set wherever practicaland connected with the shaft p by any suitable transmission. The rearaxle would then pass behind the racks, and

the beams g extend forwardly, so as to rest on a cross-piece ontheforepart of the wagon.

The wedge-shaped tube described enables the use of a straight axlerunning across the body of the cart, which otherwise would have to bebent down D-shaped to clear the body of the cart, which, however,requires considerable work without a corresponding increase in strength.In fact, such a D-shaped axle is necessarily weak at the bent parts. Soin using a straight axle a tube covering the same would have to be atleast oval to allow some play for the vertical vibrations and motions ofthe axle inside of the tube, especially so if a spring should be used onwhich the axle rests. 'lhis oval-shape tube is made wedgeshaped with thesharp edge pointed upwardly so as to prevent any sand to remain in thetop of it and so requiring the wiping oi of the same when the dump-cartis emptied. The tube serves also as a brace for the two side walls andso strengthensthe underside of the dump-cart and prevents the bulgingout of the sides by the pressure of the material. These advantages,together with the special arrangement of the sliding door at the lowerpart of the hopper-shaped body, are practical and real and serve as aspecial recommendation to those using dump-carts of the characterdescribed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
